Aprilaire Humidifier - Model 350

Having the right amount of humidity isn’t only beneficial to your home, it is also essential for your throat, skin, and your overall wellness. Exposure to inadequate humidity can dry out and inflame the mucous membrane lining your respiratory tract, increasing your risk of colds, the flu, and other infections. Also, when humidity levels are low, flu viruses develop and spread more easily.

In addition, when a home is less humid, the air will feel cooler which means you need to turn up your furnace to get your desired heat. Low humidity is also associated with dry skin and a higher risk of catching airborne diseases.

It is quite normal for your furnace to run 24/7 during the coldest months of winter. You may use thick curtains or close all your windows to try to hold heated air. While that is a good practice to save on your heating costs, it is still suggested to have a whole home humidifier, which can make the air feel warmer, allowing you to lower your thermostat settings.

Four Seasons Air Specialists is an HVAC company in Shoreview, MN that offers an array of whole-home humidifiers made by Aprilaire, one of the best in the industry.

What is Humidity?

Humidity refers to the presence of water vapor in the atmosphere. It is completely transparent, just like the rest of the gases in the atmosphere. 

Cooking, washing, bathing, and exercising are some household activities that contribute to the production of moisture. Believe it or not, breathing also brings moisture into the air. Your family and pets bring many liters of water into your home every day.  Moisture can also enter your house from the soil through the basement or crawl space.

Bugs and mold develop in areas that have humidity levels of 70-80 percent. A certain research has found that mite populations stop growing and die out when relative humidity goes under 60 percent.

In a cold weather, especially when cold outside air is heated indoors, the humidity may drop to as low as 10–20%. This low humidity can cause undesirable health effects, by drying out mucous membranes such as the lining of the nose and throat, and can cause respiratory irritation. Insufficient moisture also can affect wooden furniture, causing shrinkage and loose joints or cracking of pieces. Books, papers, and artworks may dwindle or bend and become brittle in very low humidity.

What is a Humidifier?

A humidifier is a device that increases moisture in an individual room or an entire building. In the home, point-of-use humidifiers are commonly used to humidify a single room, while whole-house or furnace humidifiers, which connect to a home's HVAC system, provide humidity to the entire house.
